Genotypes for melatonin receptor type 1A (MTNR1A) and Calpastatin (CAST) were determined by enzymatic digestion of PCR products and Calpain(CAPN) genotype detected by PCR-SSCP method in Iranian Karakul sheep. Blood samples were collected from 100 purebred Karakul sheep. The extraction of genomic DNA was based on guanidinium thiocyanate- silica gel method. PCR amplicons were digested with restri...

Homozygous grey Karakul lambs are born with a lethal genetic factor responsible for death and weaning age. When put on a high roughage diet under field conditions they develop distended, thin-walled rumens and sand impacted abomasa. Homozygous white Karakul lambs have a similar factor but survive for a longer period. Black Karakul lambs are not affected. The present study was undertaken to comp...

While the international trade in small ruminants and small ruminant products is small relative to the trade in bovine, swine and poultry products, it is still economically important. In addition to wool, it includes some unique products (such as goat and sheep milk cheeses, cashmere fibre and karakul pelts) and the sheep/goat meat trade plays a large part in sustaining livelihoods in several re...

Breed diversity is a valuable resource of the sheep industry. Crossbreeding systems use breed diversity to increase productivity relative to purebred flocks. Crossbreeding systems vary in managerial complexity and in use of beneficial effects due to crossbred ewes and lambs. Efficiency of meat production is maximized in terminal crossbreeding systems by use of specialized sire breeds to complem...

This survey was carried out to determine the infection rate of Coenurus cerebralis in Urmia abattoir, West Azerbaijan, Iran. A total of 402 sheep heads were examined and the number of C. cerebralis cysts per each head was recorded. Thirty three sheep heads were examined each month during 12 months from 2006 to 2007. Of 402 heads, a number of 75 heads (18.65%) were infected with C. cerebralis. T...

The article provides recommendations on the use of immunological methods and criteria for assessing level natural resistance, in order to select animals with high resistance. Karakul sheep sur (brown) color having a concentration common immune proteins serum blood (CIPSB) quantitative method 32–50 mg/ml semi–quantitative 1.1–2.0 conventional units, cellular immunity according skin reaction (del...

Research methods. analyzed by MspI endonuclease restriction. Results. We revealed diversity genotypes allelic variants Breeds. It found that M allele locus is...

The article presents the possibility of using waste oil obtained by repeatedly frying fish, and it in process fattening karakul. main properties purified were determined an IR spectroscopic analysis was carried out. Bleached is used emulsion greasing karakul with soft, smooth elastic leather tissue. KEY WORDS: karakul, fatliquoring, oil, emulsifier, material, acid number, vegetable oils.

The aim of this study is to determine whether or not the breed and sex factors have an effect on shape in mandibles Hamdani Awassi sheep. A total 31 were used. samples analyzed via geometric morphometric methods by using semilandmark. In study, it was determined that primary principal component accounted for 36.52% difference. According analysis, clustered significantly terms breed; whereas, th...
